4″ borehole pump made of stainless steel 304 with Delrin impellers on a ceramic support bush, allowing this pump to run dry without issues. Suitable for installation in wells with a minimum (internal) diameter of 100mm. Sand-resistant up to 250g/m3, making it suitable for wells that produce some sand. This pump delivers the maximum capacity that a 4" borehole pump can provide.
To achieve this high capacity, this pump is designed WITHOUT AN INTERNAL CHECK VALVE. If you require a check valve in the line, we recommend installing a 3″ valve.
This pump runs on three-phase power! The cable can be extended upon request. The length determines the diameter of the cable.
